| Abstract | : | Ni_3Mn alloy has the Cu_3Au type crystal structure and its magnetic properties deeply depend on the degree of its order-disorder transformation. It takes, however, a considerably long time to make order-disorder transformation occur. The alloy, named nimalloy, has been forged into a thin ribbon by using a new fabricating method that is called "Rapidly Quenching Method". It has been discoverd that the ribbon, fabricated by this method, shows a ferromagnetic characteristic after being annealed for one hour under the order-disorder transformation temperature. And it has been found that the saturation magnetic flux density and coercive force vary according to Mn composition. The former reaches 4 KG at 22 at% Mn; the latter varies from 35 to 90 Oe. The ribbon has a specific electrical resistivity of 61.7～87.5 μΩ-cm at room temperature and tensile strength of 76.0 kg/mm^2. |
